p-Ethoxyacetophenone (CAS# 1676-63-7)
Ubungozi Nokuphepha
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R26 – Kunobuthi Kakhulu ngokuhogela I-R22 – Iyingozi uma igwinywe |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. I-S28 – Ngemva kokuxhumana nesikhumba, geza ngokushesha ngensipho eningi. |

Kwethulwa i-p-Ethoxyacetophenone (CAS# 1676-63-7)
Inhlanganisela eguquguqukayo nebalulekile emhlabeni we-organic chemistry kanye nezicelo zezimboni. Le ketone enephunga elimnandi, ebonakala ngeqembu layo le-ethoxy, iwuketshezi oluphuzi olukhanyayo olungenambala ukuya kokuphaphathekile olunephunga elimnandi, elimnandi, okulwenza lube isithako esibalulekile ekwakhiweni okuhlukahlukene.
I-p-Ethoxyacetophenone isetshenziswa ngokuyinhloko njengesihluthulelo esimaphakathi ekuhlanganisweni kwemithi, amakhemikhali ezolimo, namakha. Isakhiwo sayo samakhemikhali esiyingqayizivele siyivumela ukuthi ibambe iqhaza ekuphenduleni okuhlukahlukene, okuhlanganisa i-Friedel-Crafts acylation kanye nokushintshwa kwe-nucleophilic, okuyenza ibe yisakhiwo esibalulekile sosokhemisi nabakhiqizi ngokufanayo. Ukuzinza kwenhlanganisela nokusebenza kabusha kuyenza ibe inketho ekahle yokwakha ama-molecule ayinkimbinkimbi kuzilungiselelo zocwaningo nentuthuko.
Embonini yephunga elimnandi, i-p-Ethoxyacetophenone yaziswa ngekhono layo lokunikeza inothi elimnandi, lezimbali kumakha nemikhiqizo yokunakekela komuntu siqu. Ukunyibilika kwayo ezincibilikisini ezihlukahlukene kuthuthukisa ukuguquguquka kwayo, okuvumela abaklami ukuthi bakhe uhlu olubanzi lwamaphrofayili wephunga eliheha abathengi. Ukwengeza, ukuguquguquka kwayo okuphansi kuqinisekisa ukuthi amakha agcina ubuqotho bawo ngokuhamba kwesikhathi, enikeza okuvelayo okuhlala njalo.
Ngaphezu kwalokho, i-p-Ethoxyacetophenone izuza amandla emkhakheni wama-photoinitiators wezingubo noyinki ezelapheka yi-UV. Ikhono layo lokumunca ukukhanya kwe-UV futhi iqalise i-polymerization iyenza ibe yingxenye ebalulekile ekukhiqizweni kokuqedwa okuhlala isikhathi eside kanye nekhwalithi ephezulu.
Ngokusetshenziswa kwayo okuhlukahlukene kanye nesidingo esikhulayo, i-p-Ethoxyacetophenone iwumsebenzi okufanele ube nawo ochwepheshe bezimboni zamakhemikhali, ezemithi, nezimonyo. Kungakhathaliseki ukuthi ufuna ukuthuthukisa ukwakheka komkhiqizo wakho noma ukuhlola izindlela ezintsha zokwenziwa, i-p-Ethoxyacetophenone inikeza ukwethembeka nokusebenza okudingayo. Yamukela amandla ale nhlanganisela emangalisayo futhi ukhuphule amaphrojekthi akho ezindaweni eziphakeme.
